Unit Test Project Structure

Learn how NUnit alters your existing project and learn to layout your application and test code.


This lesson focuses on how a project directory’s structure and its contents are changed when a unit test project is added, along with descriptions of what the changes mean. This lesson does not provide an overview on how to set up a unit test project as this is covered in other lessons. We’ll look at what happens under the hood when a test project is created either through using an IDE or using the console.

The lesson will also provide an overview of the best practices for the test code project structure.
